Out of equilibrium response and fluctuation-dissipation violations across scales in flocking systems
Federica Ferretti, Irene Giardina, Tomas Grigera +2
Flocking systems are known to be strongly out of equilibrium. Energy input occurs at the individual level to ensure self-propulsion, and the individual motility in turn contributes…
The Inertial Spin Model of flocking with position-dependent forces
Sebastián Carruitero, Alejo Costa Duran, Giulia Pisegna +2
We propose an extension to the ISM of flocking and swarming. The model has been introduced to explain certain dynamic features of swarming (second sound, a lower than expected dyna…
Natural Swarms in Dimensions
Andrea Cavagna, Luca Di Carlo, Irene Giardina +5
The dynamical critical exponent of natural swarms of insects is calculated using the renormalization group to order . A novel fixed point emerges, where both activity a…
Dynamical renormalization group for mode-coupling field theories with solenoidal constraint
Andrea Cavagna, Luca di Carlo, Irene Giardina +3
The recent inflow of empirical data about the collective behaviour of strongly correlated biological systems has brought field theory and the renormalization group into the biophys…
Marginal speed confinement resolves the conflict between correlation and control in natural flocks of birds
Andrea Cavagna, Antonio Culla, Xiao Feng +7
Speed fluctuations of individual birds in natural flocks are moderate, due to the aerodynamic and biomechanical constraints of flight. Yet the spatial correlations of such fluctuat…
Equilibrium to off-equilibrium crossover in homogeneous active matter
Andrea Cavagna, Luca Di Carlo, Irene Giardina +2
We study the crossover between equilibrium and off-equilibrium dynamical universality classes in the Vicsek model near its ordering transition. Starting from the incompressible hyd…
Renormalization group crossover in the critical dynamics of field theories with mode coupling terms
Andrea Cavagna, Luca Di Carlo, Irene Giardina +3
Motivated by the collective behaviour of biological swarms, we study the critical dynamics of field theories with coupling between order parameter and conjugate momentum in the pre…
Dynamical renormalization group approach to the collective behaviour of swarms
Andrea Cavagna, Luca Di Carlo, Irene Giardina +3
We study the critical behaviour of a model with non-dissipative couplings aimed at describing the collective behaviour of natural swarms, using the dynamical renormalization group.…
